| Abstract: | This paper describes testis and epididymis in 16 newborn infants. The wall of the seminiferous tubule has a basement membrane lined with the spermatogonia ( type A and type B) and the supporting or Sertoli cells. The interstitial or Leydig tell is a polyhedral cell having a large pale nucleus with one or two nucleoli, and an eo-sinophilic cytoplasm, which contains lipid droplets and brownblack granule with Sudan black B or silver stain. The Leydig cells produce hormone, mainly testosterone. Efferent ductules is lined with an epithelium composed of ciliated columnar cells and cuboidal cells. The ductus epididymis is lined with pseudostrotified columnar epithelium, that consisting of principal cells and basal cells. |
